Lori passes 80% of her tests. in the next week, lori has 4 tests. she wants to determine the probability that she passes all 4 of the tests. which simulation design has an appropriate device and a correct trial? a) let heads represent lori passing a test and tails represent lori failing a test. flip the coin four times. b) roll a die letting 1-5 represent lori passing a test and 6 represent lori failing a test. roll the die four times. c) spin a spinner that is split up into 5 sections, where 4 sections are a success of passing a test. spin the spinner four times. d) using a random digits table select one digit numbers where 0-8 is a passing grade and 9 is a failing grade. select four digits.
